Air Temperature Requirements for Conversion Varnish Curing
From contributor E:
I switched to MLC CV back in Jan. I used nitro for 18 years. I would never go back except for certain applications. The most important thing is watch your mil thickness. The way I was taught to use it was - spray one coat, walk away, go back 45 minutes later, sand, and shoot again. Walk away and go back an hour later and you won't believe how beautiful it is. Like I said watch the thickness.
From contributor W:
We switched from SW to Mohawk CV about one year ago. The SW has so much formaldehyde in it, it will sting your eyes and throat when it flashes off. The Mohawk CV is formaldehyde free (and $10/gal cheaper). The SW CV is also much harder to clean up.
From contributor R:
I haven't used the stuff in quite a few years but I had an unhappy experience due to temperature. Used it (SW brand) in a Charleston SC summer because it was specified for a particular job and loved it! Easy to spray, flowed out well and sanded freely. Yes it was nasty stuff but that is why they make respirators. I continued to use it on various products until the fall when the temp dropped a bit below 70.
The threshold was 68 if I remember correctly and at the time was not provided in the data sheet. A failure occurred as a result and I had to strip a few mahogany tops and start over- it could have been worse. Based on my experience with this product I would recommend taking the temp threshold seriously, make sure the ambient temp and the material temperature is well above the minimum.
